In a closed circuit, electricity can flow through a loop, from the battery, to the LED, and back again, causing the LED to light up. If one or more of the connections is broken (for example, one LED lead is not touching the copper tape), this creates an open circuit. Electricity cannot flow in an open circuit, so the LED goes out.

Electric circuits can be described in a variety of ways. An electric circuit is commonly described with mere words like A light bulb is connected to a D-cell . Another means of describing a circuit is to simply draw it. A final means of describing an electric circuit is by use of conventional circuit symbols to provide a schematic diagram of the circuit and its components.
The battery''s negative electrode is called the anode (ANN-ode). When a battery is connected into a live circuit (one that has been turned on), chemical reactions take place on the anode''s surface. In those reactions, neutral metal atoms give up one or more electrons. That turns them into positively charged atoms, or ions.
9.2.2 Parallel resistances and the junction rule. One of the simplest examples to analyze is the parallel resistance circuit, of which figure b was an example. In general we may have unequal resistances (R_1) and (R_2), as in c/1. Since there are only two constant-voltage areas in the circuit, c/2, all three components have the same voltage difference across them.
Impedance spectra can be described by means of equivalent circuit models, which capture the main physical processes occurring within the battery, and allow the representation to be simplified from complex impedance values measured over a broad frequency range, to a few circuit parameters [14], [15], [16].The identifiability of parameters must be …
In complex circuits, the current may not necessarily flow in the same direction as the battery arrow, and the battery arrow makes it easier to analyze those circuits.
